Key Strengths Cadillac Escalade 6.2l L87 Engine
-
Performance & Refinement
With 420 hp and robust torque, the Cadillac Escalade 6.2l L87 Engine offers strong acceleration and towing capability (often rated around 8,200–8,300 lb when properly equipped). It delivers refined V8 feel with modern fuel injection. -
Fuel Efficiency Management
Its use of Dynamic Fuel Management (DFM) allows variable cylinder control—not just V4 or V8 modes but up to 17 firing patterns that optimize fuel economy under varying loads -
Build Materials
The lightweight aluminum block and heads help offset mass of the heavy Escalade, contributing to better structural balance and handling.
Known Concerns & Failure Trends
Reliability Issues: 2022–2024 Model Years
User reports and service advisories highlight recurring failures:
-
Rod bearing and main bearing failures, often resulting in catastrophic engine shutdowns—even under 5,000 miles. Dealers reportedly facing multi-month waitlists for replacement engines Lifter oil starvation design flaws, where variable displacement hardware fails, due to inadequate oil flow resulting in seized lifters or bearings
-
Increased failure rates specifically tied to model years 2023 and early ’24, prompting a Technical Service Bulletin (TSB) and some owners reporting misaligned lifter bores
From Reddit and owner forums:
Overview of complaints:
-
Failures often under 20,000 miles, sometimes under 5,000 miles
-
Long lead times for replacement engines
-
Class‑action lawsuits and NHTSA investigations have been observed in early 2025
Which model years to prefer?
-
Earlier Cadillac Escalade 6.2l L87 Engine (2015–2020) reportedly had fewer failures and were built with older V8 architecture and Active Fuel Management (AFM) instead of DFM. Those appear more reliable—but still not immune to AFM‑related lifter issues
-
Some users suggest avoiding 2023–2024, or at least confirming the replacement engine has corrected casting codes (e.g. “N44” code on block) to indicate updated variant

Verify engine details before purchase
-
Confirm VIN 8th digit = ‘L’ and that the option code is L87 (not L86 or L94) to match your vehicle’s maintenance and emissions
-
Ask seller for block serial/manufacture code, like “N44”, to ensure it’s among the updated casting variants that reportedly fix earlier bearing/lifter issues
-
Request history for oil change intervals, use of recommended oil, and ensure parts like oil cooler lines match your year
Warranty and support
-
Many listings offer 30‑ to 180‑day warranties; longer coverage is preferable
-
OEM dealers may honor GM warranty if engine still within original coverage or under goodwill gestures
-
Be cautious: some replacement engines reportedly failed again soon after swap
Installation & costs
-
Dealership labor rates reported between $125 to $262/hour, with full swap totaling $10,000–$18,000 including labor and ancillary parts (oil pump, cooler, sensors, etc.)
-
Many owners wait 4–12 weeks for a replacement engine depending on supply chain backlog

Final Advice Before Purchase
-
Avoid buying a 2023–2024 Cadillac Escalade 6.2l L87 Engine unit unless confirmed as updated version with corrected casting code and full warranty.
-
Prefer Cadillac Escalade 6.2l L87 Engine (2015–2020) if you want reliability and fewer electronic complexities, but know it lacks DFM and may have lower output.
-
Verify oil maintenance history; many failures traced to improper service (long intervals, wrong viscosity oil, etc.).
-
Check for TSBs or recalls covering lifter bore alignments or engine replacements for your specific VIN.
-
Consider legal options if failure occurs under warranty or within lemon law timeframes—buyers report dealers often slow to compensate despite corporate assurances .
In Summary
The Cadillac Escalade 6.2l L87 Engine is potent, technologically modern, and well-suited to towing and upscale driving—but some production runs (notably 2022–2024) suffered engine failures tied to oil flow and bearing defects. If you’re shopping for an L87 engine:
-
Confirm specific casting revision, seller’s warranty, and vehicle compatibility.
-
Be aware of long install times and potential high service costs.
-
Consider older Cadillac Escalade 6.2l L87 Engine variants for better documented reliability, albeit slightly less fuel-efficient.
